Description of problem: I have KDE set to Hibernate after 89 minutes. At some point in the recent past it has stopped attempting to hibernate at all. The only thing I see related in any logs comes from .xsession-errors: powerdevil: Unsatisfied policies, the action has been aborted powerdevil: Failed to start suspend job "org.freedesktop.login1.SleepVerbNotSupported" "Sleep verb not supported" Version-Release number of selected component (if applicable): powerdevil-5.5.5-1.fc23.x86_64 How reproducible: Always Steps to Reproduce: 1.Set KDE to Hibernate after X minutes 2.Wait X minutes 3. Actual results: Nothing happens Expected results: System hibernates Additional info:
In your active plasma session, can you open a konsole, and run (all one line) qdbus --system org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.CanHibernate
[long@kite ~]$ qdbus --system org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.CanHibernate na [long@kite ~]$
OK, so as far as systemd/logind is concerned, you cannot hibernate. This can be for several reasons (session permissions, swap too small, etc...) Curious, what does this say? qdbus --system org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.CanSuspend
[long@kite ~]$ qdbus --system org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.CanSuspend yes [long@kite ~]$
My only guess is that maybe you don't have enough swap to save state, I'm not sure if logind does any checks beyond that to support hibernation. I'm not sure of the specific requirement, but I think it's approximately swap > ram. So, can confirm your current swap is larger than RAM ?

OK, triaging to systemd, I don't know why org.freedesktop.login1.Manager.CanHibernate dbus call isn't returning yes
Is the kernel parameter resume=$your_swap_partition set? If so what happens when you run systemctl hibernate from the command line?
strange, I rebooted and now the qdbus command says I can hibernate and 'systemctl hibernate' works fine. I will see what happens when I leave it idle overnight now.
It hibernated fine now. Any ideas on why CanHibernate was not yes previously?
Went for extended lunch, came back, found hibernate did not happen and qdbus once again reports "na"
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
